摘要：The diatom flora of the shallow lakes in border among Telaga Pengilon and Telaga Warna is poorly known. This study focuses on the composition of diatom assemblage in order to know the diversity and dominancy pattern for paleolimnological study. Total 103 taxa was observed, dominated by Eunotia formica 12,27%, Eunotia tropica 9,9%, Pinnularia gibba 4,3% and Frustulia saxonica 4,9%. Based on dominant species Eunotia formica occurring among the epiphyton and found in standing or slow-flowing dystrophic to oligotrophic waters with specific pH 5.6-7,4. But, in the top soil dominated by Eunotia bilunaris var. linearis about 14,50% and it was commonly found in acidic, flowing or standing waters with pH 2.8-3.5. The lowest diversity index represent at 102cm indicated that there is no diatom recorded, it caused by volcanic activity because Dieng area surronded by mountain area also has 31 eruptive history. The results of this research mention that in the border area has influence from both lakes so the pH fluctuated. Overall, diatom assemblages were similar to those Warna and Pengilon.
